Of course with the original Dropbox based sync, a concern is that Dropbox itself isn't set in amber, at some point it might get rug pulled and sadly 1P never introduced WebDAV or some other self-hosted option before subscription/VC fever set in. And I suppose that macOS continues to move along too. 1P7 on the latest and final version is Apple Silicon native and through a lot of major transitions doing nothing exciting, so it might well keep running for a long time. But the browser extensions will probably stop working at some point which is going to be another big line for a lot of people, and legitimately because it's a not insignificant bit of security.

Anyway, I mean, not like one couldn't keep running it a long time via various layers, but I figure probably time to at least survey the landscape on moving on :(
